Induction improves output for Blue Wave

A heating solution based on EFD Induction’s Minac induction heating system has succeeded in improving output for Blue Wave.

 

Blue Wave is of the world’s largest manufacturers of rigging hardware for the marine, architectural and industrial markets.

 

The new solution, which is installed at Blue Wave’s production facility in Haderslev, southern Denmark, uses an EFD Induction Minac 18/25 to heat workpieces such as shackles, bolts, cones and fork terminals. ‘The goal,’ says Allan Klostergaard of EFD Induction Denmark, ‘is to heat the workpieces to around 1,100 °C [2,010 °F ] in order to achieve austenite transformation—a change in the workpiece’s micro-structure that enahnces malleability prior to hot forging.’

 

Blue Wave’s new Minac system has a continuous output power of 18 kW and an intermittent maximum power of 25 kW. It also, like all EFD Induction Minacs, features automatic electronic matching. This optimizes energy transfer into the workpiece during the entire heating cycle.

 

According to Blue Wave’s head of production Helmer Knudsen, the new Minac has had a major impact on productivity. ‘The Minac has significantly reduced heating times. At the same time, we can now heat larger workpieces compared to our previous heating system.’

 

‘But higher output isn’t the only benefit brought by the Minac,’ says Klostergaard in conclusion. ‘The system’s electronic controls help ensure precise repeatability. This of course helps Blue Wave maintain the high quality standards for which they are so well known.’
